选择ＣａＯ－ＳｉＯ２－ＦｅＯ为基本渣系，对高碳熔铁脱磷进行实验，研究了高碳熔铁脱磷过程中碳和磷的变化，比较在不同温度和溶剂的条件下，对高碳熔铁脱磷的影响．实验表明：熔铁初始碳含量的高低对前期脱磷影响不大．但终点碳含量的高低影响回磷．ＢａＯ在高碳脱磷过程中能有效地抑制回磷．
CaO-SiO2-FeO was selected as the basic slag system to study the dephosphorization of high-carbon molten iron. The changes of carbon and phosphorus during the dephosphorization of high-carbon molten iron were studied. Under different temperature and solvent conditions, Effect of molten iron dephosphorization. Experiments show that: the initial level of molten iron has little effect on dephosphorization. However, the level of carbon content at the end of the return of phosphorus. BaO in the high-carbon dephosphorization process can effectively inhibit the return of phosphorus.
